You are on your way. The more you make, the better you will get at it. Don't give up.
Woodworking and perfecting your skills is a journey, not a destination. Enjoy the trip.
We all started with simple projects and worked up from there. Coat trees and book cases are a good beginning. The coat tree looks pretty good to me, but I would have used slightly smaller dowels. To me, they just look too big, but they should work fine. We refine our tastes as we progress. I'm looking forward to your next project photos. Thanks for posting.
The trip is why I started a few years ago, for various reasons. Sometimes it feels like I should be farther along, but I also know how much time I'm able to put into this with everything else in life. There may be several months that go by before I'm really able to do much work on anything.
I agree that the dowels are big. At the time I was worried about them snapping from the weight of the coats. I would be surprised if these did. The dowels also took a surprising amount of time to make, until I decided to turn my plane upside down and use it like a vegetable slicer.
Any project that you feel is worth showing is a good project.
Even Norm Abrahams started by sweeping the floor.
But from a practical point of view, I think the bottom cross pieces are not wide enough for the height. 2 or three coats on one side will tip it over.
Wider or heavier will make it safer to use.
These are good points regarding safety/engineering.
The base pieces are ~20.5" long. The top dowels end before the base pieces do so the coats are still over the base. I did a crude center of gravity estimate of the empty unit and it's ~6" above the little vertical "supports" coming up from the base. The empty unit is solid mahogany and weighs ~16.5 lbm.
There were three coats on the wall before I made the tree. Two are just raincoats, but the black one is a smaller Carhartt jacket. I put all three on the same side, with the two heavier coats on top and gave the unit a bump to simulate (me) accidentally shouldering it, and it did wobble slightly but didn't tip. Right now the three coats are all on the same half but different dowels, with no signs of instability.
